DRAM（Dynamic Random Access Memory），即动态随机存取存储器，最為(wèi)常见的系统内存。
几乎所有(yǒu)的 DRAM 作(zuò)為(wèi)计算机系统中(zhōng)的离散元器件存在。DRAM 的硅工(gōng)艺经过显著地定制，因此其无法与 CPU 一起集成。有(yǒu)许多(duō)样式的 DRAM 可(kě)满足市场的各种需要。双数据速率 DDR 存储器是台式机和服務(wù)器计算机中(zhōng)最常见的 DRAM 类型。DDR4 是最新(xīn)一代的 DDR 存储器。低功率 DDR (LPDDR) 是移动和嵌入式系统首选的存储器技(jì )术。还有(yǒu)其他(tā)类型的 DRAM。
DRAM 单元只是一个存储電(diàn)容器和访问晶體(tǐ)管。一个DRAM的存储单元存储的是0还是1取决于電(diàn)容是否有(yǒu)電(diàn)荷，有(yǒu)電(diàn)荷代表1，无電(diàn)荷代表0。但时间一長(cháng)，代表1的電(diàn)容会放電(diàn)，代表0的電(diàn)容会吸收電(diàn)荷，这就是数据丢失的原因；刷新(xīn)操作(zuò)定期对電(diàn)容进行检查，若電(diàn)量大于满電(diàn)量的1/2，则认為(wèi)其代表1，并把電(diàn)容充满電(diàn)；若電(diàn)量小(xiǎo)于1/2，则认為(wèi)其代表0，并把電(diàn)容放電(diàn)，藉此来保持数据的连续性。
